Description
Technical field
The present invention relates to a kind of parts of CD drive.
Background technology
CD drive (abbreviation CD-ROM drive) is the device that can read the data of optical disc storage, and CD is meant a kind of carrier that promptly passes through principle sense datas such as reflection of light, refraction, polarization with method of optics.Along with the continuous development of science and technology, CD-ROM drive has been widely used in computing machine or the AV device, and computing machine or AV device can read the data that write down in the CD by CD-ROM drive, can also write the data that will deposit for the CD-ROM drive with imprinting function.CD-ROM drive with imprinting function reads the data in the CD or write data in CD by its optical read-write head.The method that wherein reads is the laser that utilizes optical read-write head to send, and focuses on the optical disc surface (being the information faces of CD) of storage data, follows the laser of the different reflectivity that reflects by reception, the data of identification record in disc.The method that writes with read just in time opposite, be that different pieces of information is processed into the different laser beam of energy, focus to optical disc surface (being the information faces of CD), cause it to produce physics or chemical change, the light reflectivity of optical disc information face is changed, thereby information is recorded on the CD.But no matter be in reading of data or when writing data, optical read-write head all must remain the laser beam of sending good focusing on CD, this movement locus face that just requires optical read-write head not only will with the information faces keeping parallelism of CD, also to keep a relatively-stationary distance simultaneously with the information faces of CD, when writing (recorded information), this distance just seems particularly important.Optical read-write head driving device has bottom deck assembly, rotating moving part, slides drive disk assembly, guide rod assembly and optical read-write head.Rotating moving part is used for supporting CD and do high speed rotary motion when making its work so that optical read-write head reads the data in the CD or write data in CD; The guide rod of guide rod assembly is used for supporting optical read-write head and is its guiding, can reach to the inclination angle between the information faces of the movement locus face of optical read-write head and CD with apart from the purpose of controlling by the adjustment to guide rod; Sliding drive disk assembly is used for making it along the guide rod easy motion to the optical read-write head outputting power.Chinese patent application 02241182.8 discloses a kind of " the two guide rod three-point fix adjusting gears of CD-ROM drive ".As shown in Figure 1: this device has CD-ROM drive bulk 10, first guide rod 20, second guide rod 30, positioning body 40 and pressing plate 50; CD-ROM drive bulk 10 in this device is the bottom deck assembly in the above-mentioned optical read-write head driving device, and first guide rod 20, second guide rod 30, positioning body 40 and the pressing plate 50 in this device is the guide rod assembly in the above-mentioned optical read-write head driving device; Wherein first guide rod 10 and second guide rod 20 place the both sides of CD-ROM drive bulk 10 respectively, make positioning body 40 can press on the two ends of first guide rod 10 and an end of second guide rod 20, and an end of the two ends of first guide rod 10 and second guide rod 20 places 14 of corresponding backup plates respectively, and utilizes pressing plate 50 to compress positioning body 40; CD-ROM drive bulk 10 is provided with respectively with the corresponding screw hole 16 of an end of the two ends of first guide rod 10 and second guide rod 20 and screw 17 interlockings is arranged on screw hole 16; The other end of second guide rod 20 is plugged in the holder 13 of CD-ROM drive bulk 10; The position of regulating guide rod by screw and positioning body 40 makes the movement locus face of optical read-write head be parallel to the disc information face.The inclination angle that can only regulate the movement locus face of optical read-write head by this regulating device makes it to be parallel to the information faces of CD, and can not regulate distance between the information faces of the movement locus face of optical read-write head and CD, therefore precision that should distance just depends on the manufacturing accuracy of holder 13, want accurately to control the manufacturing accuracy that distance between the information faces of the movement locus face of optical read-write head and CD just must improve its holder 13, thereby higher to its manufacture process requirement, cause cost to increase.Drive the optical disk high-speed running during spindle motor of rotating moving part work simultaneously and can produce vibrations, these vibrations can influence the stability of CD-ROM drive work.
